Текст:
Last weekend, my class went on a field trip. It was a great success, and we became famous on the Internet after posting photos of our "Trash challenge." There is a big national park next to my town. People go fishing and rock climbing there on weekends. Some people just go and have picnics. Trash is a problem. On Mondays it's usually covered in a whole lot of horrible plastic bags, cups, and empty cans. This term in school we're learning about the environment. You know, things about recycling and reducing waste, and taking care of the planet. We talked about what we could do as a class to help. First, we all came up with ideas. There were many good ones, like having a campaign to clean the oceans and save the whales or helping a charity to take care of animals and plants that are in danger of extinction. In the end, we decided that it was best to concentrate on something that was close to home and easy to do something about. We all got permission from our parents, and our teacher booked a bus. On the actual day, we each took four empty trash bags and gloves to help us with our new goal. Most of it was easy. There were some really disgusting things that needed to be picked up, and one person cut themselves with a broken jar. The rest went quite quickly. In just a few hours, all the trash had disappeared, and our bags were all full. We took pictures before and after. A few days later in class, we recorded a video that showed everyone what we had done and invited students from all over the world to accept the challenge. I'm looking forward to watching their videos!
